Diagnosis: Distinguished from known congeners by shapes of procursus ( Fig. 5A–C View Figure 5 ; with subdistal ventral sclerite, partly semi-transparent flat tip) and by armature of male chelicerae ( Fig. 5G, H View Figure 5 ; frontal apophysis with wide and flat tip, in frontal view slightly bifid; similar to N. poma ); from some congeners also by bulbal processes ( Fig. 5D–F View Figure 5 ; ventral apophysis distally slender, curved towards ventral, same length as embolus) and by epigynum and female internal genitalia ( Figs 5I View Figure 5 , 6 View Figure 6 ; epigynal plate with indistinct posterior and anterior median indentations; internal genitalia with posteriorly wide open ‘receptacle’; similar to N. guirnalda ).
Type material: ARGENTINA – Jujuy: • ♂ holotype; between San Salvador and Purmamarca, ‘site 2’; 23.8849° S, 65.4613° W; 2150 m a.s.l.; 16–17 March 2019; B. A. Huber and M. A. Izquierdo leg.; LABRE-Ar 584 • 3 ♂♂, 4 ♀♀ GoogleMaps , paratypes (one male used for SEM); same data as holotype; ZFMK Ar 23883 GoogleMaps .
Other material examined: ARGENTINA – Jujuy: • 14 ♀♀, in pure ethanol (two females used for SEM; three female prosomata used for molecular study); same data as holotype; ZFMK Arg 178 GoogleMaps • 2 ♀♀; same data as holotype; LABRE-Ar 537 • 1 ♂ GoogleMaps , 3 ♀♀, in pure ethanol; between San Salvador and Purmamarca , ‘site1’; 23.8866° S, 65.4588° W; 2100 m a.s.l.; under rocks; 16–17 Mar. 2019; B. A. Huber and M. A. Izquierdo leg.; LABRE-Ar 549 GoogleMaps • 2 ♀♀, 1 juv., in pure ethanol; same data as preceding; LABRE-Ar 559 GoogleMaps .
Etymology: The species epithet colina (Spanish for ‘hill’) is taken from Pablo Neruda’s poem ‘Poema 1’; noun in apposition.
Description
Male (holotype). Measurements: Total body length 1.75, carapace width 0.72. Distance PME–PME 70 µm; diameter PME 50 µm; distance PME–ALE 20 µm; distance AME–AME 15 µm; diameter AME 40 µm. Leg 1: 5.94 (1.60 + 0.27 + 1.60 + 1.77 + 0.70), tibia 2: 1.37, tibia 3: 1.10, tibia 4: 1.50; tibia 1 L/d: 21.
Colour (in ethanol): Prosoma and legs mostly pale ochre-grey; ocular area, thoracic groove, and clypeus light brown; legs without dark rings; abdomen monochromous grey.
Body: Habitus as in N. poma (cf. Fig. 1B View Figure 1 ). Ocular area barely raised. Carapace with indistinct thoracic groove. Clypeus unmodified except for pair of indentations for genital bulb at rest ( Fig. 7A View Figure 7 ). Sternum wider than long (0.52/0.36), with pair of distinct anterior processes near coxae 1. Abdomen globular.
Chelicerae: As in Figure 5G, H View Figure 5 ; pair of frontal apophyses directed downwards, with slightly bifid tip slightly flattened in lateral view ( Fig. 7A, C View Figure 7 ); stridulatory files on pair of low lateral protrusions ( Fig. 7C View Figure 7 ).
Palps: As in Figure 4 View Figure 4 ; coxa unmodified; trochanter with indistinct ventral projection; femur cylindrical, only slightly widened distally, proximally with indistinct retrolateral hump and prolateral stridulatory pick (modified hair); patella short; tibia globular; procursus ( Fig. 5A–C View Figure 5 ) simple, in lateral view slightly directed towards dorsal, with distinctive subdistal ventral sclerite and partly semi-transparent flat tip; genital bulb ( Fig. 5D–F View Figure 5 ) with ventral apophysis distally slender, curved towards ventral, embolus partly membranous.
Legs: Without spines and curved hairs; with slightly higher than usual density of short vertical hairs on tibia 1 ( Fig. 8A, B View Figure 8 ); retrolateral trichobothrium of tibia 1 at 70%; prolateral trichobothrium absent on tibia 1; tarsus 1 with seven to eight pseudosegments, distally distinct. Variation (male): Tibia 1 in five males (including holotype): 1.50–1.73 (mean 1.62). Abdomen variably dark.
Female: In general, similar to male but sternum without pair of anterior humps and tibiae with few vertical hairs. Tibia 1 in nine females: 1.37–1.63 (mean 1.49). Epigynum ( Fig. 6A View Figure 6 ) anterior plate weakly protruding, with anterior and indistinct posterior indentations; posterior plate large, simple. Internal genitalia ( Figs 5I View Figure 5 , 6B–D View Figure 6 ) with posteriorly wide open ‘receptacle’.
Distribution: Known only from type locality in Jujuy, Argentina ( Fig. 3 View Figure 3 ).
Natural history: The spiders were found by turning stones and rocks on an arid slope ( Fig. 45A View Figure 45 ). They shared the microhabitat with a second species of Ninetinae , an unidentified species of Guaranita . They seemed to prefer large stones and rocks that were close to vegetation. When disturbed, they ran rapidly but remained on the rock. No webs were seen.
